I would like to talk about one thing that I can not live without, which is my cell phone First of all, it is really convenient if we have a cell phone. Because we can use our cell phone to do anything. Like playing video games when I am on the subway or buses. Watching movies and for me I usually watch movies on the subway by cellphone. Studying like every day I listen to storytelling on some sort of apps. , watching movies even pay utilities like electricty bill water bill and when I want to go out for fun, I can order a taxi by app Secondly, it saves your money because long time ago we need to text messages using money, now we can send our messages on wechat. It won't cost you anything. I still remembered when I was in university, I need to charge my phone for minutes if I wanted to have enough time to chat with my friends. Since our cellphone is more smart, so we can contact our friends or parents at any time that you want. Thirdly, it is free from stealing, We used to pay money in cash when we had dinner or bought some food or snacks at the restaurants or shopping mall, now we only pay money by alipay or wechat. So we do not need to worry about that we forget to take the money or being stolen by people.
